Omega - Batarian Bartender

This side quest goes down in the VIP section of the Afterlife (near Lower Afterlife) at the northeastern segment of the map. You won't be able to get into the VIP area of the club via the primary entrance. Instead, seek out an out-of-the-way corridor running westward from Kenn's Salvage, which will eventually wind its way towards the VIP section's alternate entrance/exit. Once you arrive there, head to the oval-shaped bar and seek out the bartender, Batarian named Forvan. When you "speak" with him, no words will be exchanged. Rather, you can select to have a drink, and he'll serve one up to you. Unfortunately, when you drink it, you'll pass out on the ground. Just what has this Batarian done?

When you come-to, you'll find yourself in the corridor back near Kenn's Salvage. A human male will be standing over you, along with your team. This human is named Henner. Once you've stumbled back up to your feet, Henner will explain why Forvan poisoned you. It appears that some of Forvan's Batarian friends were recently killed by a group of humans, and now he poisons any human that comes into the VIP section of the bar. Making matters worse, each human that's been poisoned leading up to your encounter with Forvan had been outright killed, leaving you as the only survivor. Speak with Henner as you want, and then get up. It's time to head back to the VIP section of the bar, to take care of business.

Once you arrive back at the bar and speak with Forvan, he'll claim not to recognize you and offer up a drink. It's a this point that any number of things can happen. We opted to take the Paragon route through this, calling out Forvan for poisoning his customers. It's at this point that a Turian walks up to inquire about this poisoning. Things get out of hand, Forvan pulls a pistol, and the Turian does him in once and for all. However, if you choose the neutral or Renegade paths through this side quest, things can end a little differently for you. Naturally, how you proceed is entirely up to you, but once Forvan has been dealt with (one way or the other), this side quest will effectively conclude.
